Require to create and initialise a custom Global Variable at user login time (session Start time)

Hi All

We are doing form personalization of Requisition Form.

We have enabled the line level DFF and I have attached a Value set which references the item name in the where clause.

However, when I open the requistion in Auto Create / Requistion Summary & PO Summary, Error being prompted that item name doesnot exist.

As an alternative, I have tried to capture the item name in a Global Variable and modified the Value set to refer to it instead of the item name.

But still faced with similar problem on all the above 3 forms and the Requisition form too when retrieving a existing requisition.
